The sale of ivory is banned in most parts of the world but demand has been on the rise across parts of Asia over the past few years. That has led to a thriving black market, which is supplied by the illegal poaching of elephants throughout Africa. In the past decade, poachers have slaughtered thousands of elephants to harvest their tusks. As a result, the creatures are now endangered across much of the continent.

Tanzania’s stockpile is the result of tusks being collected following the natural deaths of elephants throughout the country, but conservationists say they still shouldn’t sell off all of that ivory. Critics of the plan fear that flooding the market with 100 tons of ivory would only serve to confuse consumers, many of who aren’t even aware that it is illegal to purchase in the first place. They say it sends the wrong message at a time when they are trying to educate people about poaching and the illegal ivory trade. Instead they recommend that Tanzania destroy its hoard of ivory, something that the country Gabon did earlier this year.

As if the sale of ivory wasn’t enough to draw the ire of conservationists, Tanzania has also said that it would like to remove elephants from the list of the most endangered species. That move would effectively reduce the level of protection given to the animals and allow for commercial big game hunting and even the trade of hides and live animals.

For a cash strapped country like Tanzania, the sale of this ivory would bring in millions of dollars in revenue. But if it further fuels the ivory trade and could potentially increases poaching, the price of the sale could ultimately be much higher than anyone wants to pay.
